About this tag
Westermo is a vendor of industrial networking equipment, including managed switches and routers that run the WeOS 5 operating system. Recent discussions on WindowsForum highlight critical security vulnerabilities in WeOS 5, such as CVE-2025-46419, a remote denial-of-service flaw triggered by a crafted ESP packet when IPsec is enabled, and CVE-2025-46418, a high-severity OS command injection vulnerability exploitable via the administrative interface. These issues are documented by both Westermo and CISA, emphasizing the need for OT-IT convergence teams to prioritize patching to WeOS 5.24.0 and apply mitigations to protect critical infrastructure.
